Novel ethyl thiourea compounds 1a – 1f have been synthesized in good to high yields. The structure of all compounds was identified using FT-IR, ¹H NMR, ¹³C NMR, and ESI-Mass. The compound 1-ethyl-3-(3-methoxyphenyl) thiourea 1d was obtained in crystalline form by recrystallization from DMSO. However, single crystal X-ray analysis revealed that the 1d molecule crystallized in a monoclinic crystal system with space group of P21/n and the unit cell dimensions are a = 11.0797(7) Å, b = 8.6081(6) Å, c = 11.9698(7) Å, α = 90°, β =104.543(2)°, γ = 90°, Z = 4 and V = 1105.04(12) ų_. The preliminary optical sensor properties for metal ions of 1a – 1f were investigated using naked-eye. The results determined that all compounds have the ability as naked eye sensors for mercury (Hg) and argentum (Ag) metal ions.
